I have been involved in virtualization projects for about ten years now. In that time I have had the opportunity to track my own list of best practice items. It's a list I share freely with customers that seek out virtualization advice. I can tell that virtualization (and Cloud) efforts are on the rise simply by the number of requests I get for help, specifically for virtualizing SQL Server.

I like to call this list my "facepalm" special, as any one of these essentially triggers a facepalm reaction. They have helped my customers in the past and I am certain they will help you.

    Virtualizing SQL Server: 8 Things to Avoid Virtualizing SQL Server: 8 Things to Avoid Presentation Transcript

    • Virtualizing SQL Server: 8 Things To Avoid Thomas LaRock Technical Evangelist Confio Software
    • 1. Build Your Own • Don’t recycle old hardware for use as a new production host • If the hardware is old now, imagine how old it will be in another 18 months • Due to licensing costs, it may be cheaper to buy new hardware and provision as a host http://www.confio.com/freetrial 2
    • 2. No Performance Expectations • You need to set performance SLAs • You do this with baselines • Measure logical I/O and CPU costs for your queries http://www.confio.com/freetrial 3
    • 3. Select Wrong Disk Choice • RDM v VMDK; which one do you want? • Know the differences in RAID as well • Understand what can cause “noisy neighbor” syndrome http://www.confio.com/freetrial 4
    • 4. Thin Provisioning • If you don’t have room now, what makes you think you will later? • Important to know what you actual sizes are, otherwise recovery may be impossible http://www.confio.com/freetrial 5
    • 5. Over-allocation of Memory and/or CPU • It leads to over-commit, which is often bad for performance • Allow for 1.5:1 vCPU to logical core ratio • Do not over allocate memory http://www.confio.com/freetrial 6
    • 6. Trusting O/S Counters • Standard counters offer no visibility to the Hypervisor layer • Need to examine VM, Hyper-V specific counters • Understand if bottleneck is with host, guest, or internal to database engine http://www.confio.com/freetrial 7
    • 7. Running It All At Once • Important to know your workloads • vMotion can help • Leave room for growth and movement http://www.confio.com/freetrial 8
    • 8. Capacity Planning • Often a futile effort • Business needs shift quickly, throwing out all your metrics that try to predict growth • Need to have room to grow, otherwise planning won’t matter http://www.confio.com/freetrial 9
    • For More Information • http://blogs.vmware.com/apps/2011/11/virtualizedexchange-storage-vmdk-or-rdm-or.html • http://www.vmware.com/files/pdf/solutions/SQL_Ser ver_on_VMware-Best_Practices_Guide.pdf • Read more at confio.com/logicalread http://www.confio.com/freetrial 10
